Abstract

PISTON D’EQUILIBRAGE ET D’ETANCHEITE, CIRCUIT DE REFROIDISSEMENT ET PROCEDE ASSOCIES Le piston d’équilibrage et d’étanchéité pour un motocompresseur intégré comprenant un piston d’équilibrage (50) destiné à être monté sur un arbre (38) du motocompresseur pour compenser la pression différentielle s’appliquant sur des roues (34, 35, 36, 37) d’une section de compression du motocompresseur entre la pression d’aspiration et la pression de refoulement, et un dispositif d’étanchéité (51) entourant le piston d’équilibrage et destiné à être monté sur le carter (31) du motocompresseur (30) pour rendre étanche la section de compression. Il comporte en outre un orifice d’extraction (52) de gaz, la position axiale de l’orifice d’extraction étant déterminée de sorte que la valeur de la pression du gaz prélevé est égale à une valeur prédéterminée inférieure à la valeur de la pression de refoulement. Figure pour l’abrégé : figure 2BALANCING AND SEALING PISTON, COOLING CIRCUIT AND ASSOCIATED METHOD The balancing and sealing piston for an integrated motor-compressor comprising a balancing piston (50) intended to be mounted on a shaft (38) of the motor-compressor for compensating the differential pressure acting on wheels (34, 35, 36, 37) of a compression section of the motor-compressor between the suction pressure and the discharge pressure, and a sealing device (51) surrounding the balancing piston and intended to be mounted on the casing (31) of the motor-compressor (30) to seal the compression section. It further comprises a gas extraction orifice (52), the axial position of the extraction orifice being determined such that the value of the pressure of the gas withdrawn is equal to a predetermined value lower than the value of the discharge pressure.
